But last night Demi Moore was finally overshadowed - by her own daughter.

The still-stunning actress simply could not compete with Rumer Willis's luminous skin and youthful beauty.

However, as Demi is 47 and her daughter is just 21, this is hardly surprising.

Glowing Rumer wore a youthful, on-trend outfit, while her mother opted for a timeless black number and a deep tan

The glamorous pair were on the red carpet at the premiere of Rumer's first film Sonority Row.

Both opted for classic black outfits - a ruffled silk LBD for Demi and trousers and belted lace jacket with a cutaway front for her daughter, whose father is Bruce Willis.

Rumer looked particularly demure with her hair swept back in a low ponytail.

Demi's choice of outfit was rather more understated than if she had been the leading lady. However, the pair still looked more like sisters than mother and daughter.

The actress has furiously denied that her astonishingly youthful
appearance is down to plastic surgery, despite persistent rumours that
she spent at least £200,000 remodelling her face and body.

Sisters?

Rumer arrived at the Arclight Theatre in Hollywood with boyfriend
Micah Alberti but told how she was more worried about her little
sister's opinion of the film than her famous parents.

She said 15-year-old Tallulah is 'the most opinionated of the bunch' in her family.

Rumer said: 'I hope my parents like it, I mean that's what any kid kind of hopes
for, honestly I think the biggest opinion I'll be looking for is my
little sister's because that's basically the demographic.

'She will be honest, she'll be like, "Ru, it was terrible" or something.'

And, unsurprisingly, seeing her parents act in films inspired her own ambitions.

She
said: 'Do you know what? It was just the kind of thing that I always
wanted to do, there was never really one defining moment that I had.

Demi Moore stole the attention from the film's leading ladies. Briana Evigan, Rumer's co-star, wore a fishtail dress which was also black

'I
grew up around it and I just always knew it was something that I wanted
to do. I always knew that I wanted to be a part of it too, it looked
like a fun group to get to hang out with.'

But she doesn't think
her sisters Tallulah and Scout, 18, are interested in following her
into acting.

'They're doing their own thing right now,' she said.

The film is a step away from her father's action hero antics and more towards her mother's style of acting.

Sorority Row is about a group of sorority sisters who try to cover up the death of their
house-sister after a prank gone wrong, only to be stalked by a serial
killer.

It is is out in cinemas on September 9.
